Protects a three-phase distribution line against earth faults.
This four-pole residual current circuit breaker protects three-phase circuits up to 25 A. It takes up 4 modules of width in the board and runs on a 400/415 V supply at 50/60 Hz.
Earth leakage protectionOpens its contacts and disconnects the circuit on an earth fault.
Load currentCarries up to 25 A across four poles.
Sensitivity typeWorks as an AC type against alternating residual currents.
Space in the boardA 4 module wide modular housing fits the distribution board.
Supply compatibilityOperates at a 400/415 V supply and a 50/60 Hz frequency.
Insulation voltageWithstands up to a 500 V insulation voltage.
